Abstract

The invention provides a large bus rollover early-warning device and method. By analyzing the actual height of center of mass of a bus, the horizontal position of the bus and the running speed of the bus, a steering angle threshold of a steering wheel operated by a driver is obtained to directly show which operation is safe; therefore, the driver can preferably experience the safe steering wheel steering angle so as to enhance the driving safety. When the steering wheel steering angle exceeds a safe range, a control unit sends a signal and a buzzer can give an alarm to remind the driver of safe operation; therefore, the bus rollover risk is reduced.

Description

technical field [0001] The invention relates to a vehicle safety early warning method, in particular to a large bus rollover risk early warning device and method. Background technique [0002] With the continuous development of my country's automobile industry and the improvement of road traffic facilities, the speed of automobiles continues to increase, resulting in a large number of traffic accidents, casualties and huge economic losses. Therefore, the safety of automobiles has become more and more popular. Pay attention to. Some vehicles, such as large passenger cars, medium and heavy trucks, and heavy-duty semi-trailers, are prone to rollover accidents when turning at high speeds and when the diameter of the curve is small due to their high center of mass position, large mass, and large volume. The damage caused by rollover accidents is serious, and it is an important issue in the field of road traffic safety and vehicle safety research. For example, the Chinese patent ...
